IMPROVEMENT IN s'roves.

.To all whom it may concern:

Be it known that I, WILLIAM BIeKEI., of Pottsville, inthe county of Schuylkill and State 'of Pennsylvania, have invented a new and nse. Aful Improvement in Fire-Boxes for Stoves and Furnaces; andy I do hereby declare that the following isa full, clear, and exact description of the same, reference being had to the accompanying drawings, making a part of this specificatdon, in which- Figure 1 is a vertical section of my inven-A tion, taken in the line w w, Fig. 2; Fig. 2, a plan or top view of the same. Fig. 3 is a frontview of a portion of the grate.v

. Similar letters of reference' indicate corresponding parts in the several figures.

. The object vof this invention is to facilitate the burning of ne coal (dust) in stoves and furnacesz and it-consists in an improvement on an arrangement for the same purpose for which Letters Patents were granted to me bearing date October 14, 1862.

To enable4 those skilledl in the art to fully understand and construct my invention, I will proceed to describe it. v

A represents a stove o'r furnace, which may be of rectangular or any proper forni; and B is the tire-grate, placed `fin t-he lower part of the stove or furnace, and formed of a series of Vhorizontal parts, a, vertical partsv b, and horizontal parts c, the parts a being some distance above e and connected by the vertical parts b. The latter parts, i), are perma'nently cong of the upper horizontal parts, a. The grated plates c rest on ledges d at the lower parts of b, so that they may be drawn outl from between them when, necessary, through apertures c', as represented in Fig.3. The upper horizontal parts, a, are not in line with the lower horizontal parts c, but are directl y over the spaces between them, as shown clearly in Fig. 1. By this arrangement it will be seen that a large area isgiven' the firegrate', and consequentlv a far greater volume of air can be admitted through the grate than if made ilat or in a plane, as usual. This will The iiregrate may be composed of parallel bars, as usual, a requisite space being allowed between the bars.

C represents a series of tubes which pass horizontally through the stove or furnace a short distance above the fire-grate B. These tubes C areopen at both lends, so that they may communicate with the air, and a register, D, lmay be fitted over their ends, at the outer side of the stove or furnace, so as to regulate the admission of air into them as` may be required. The tubes C are perforated, as shown at a', so that the air which passes into them may be introduced into the body or mass of the fuel. This air which passes into the fuel, in connection with that which passes up through the tire-grate, is snftieient to insure a-perfect or thorough combustion, even when coal dust i-s used is a fuel.

I would remark that the tubes or ventiducts C may be made ofcast-iron' covered with fire-brick or other suitable material to pre'- vent them. from being burned out.

' Having thus described myinvention, what I claim as new, and desire to secure by Letters Patent, is

l. A barred or perforated grate'consisting of upper' horizontal plates, a a ,vertical plates b b b, lower horizontal plates, c c, sliding in and out through apertures c', all as herein' shown and described, and for the purposes specified. v f

' 2. The pipes C C C, extended 4'completely through the tire-place above the grate B, open at both ends, and provided with a series of apertures, a, to provide a more free and full supply of air to the fuel when used in combinationwith registers to open or close either .end of all the pipes simultaneously, as explained.
